drawing machine or hand scraper for comtpletely emptying the oven.

As heretofore constructed, the door jambs of these ovens are curred in their inner surfaces atand -above the plane of the floor so that it is impossible to extend a straight line through any partof the oven door from any point on its side wall without pocketing more or less of the oven space. The rake or fork of a mechanical coke drawer cannot operate in space thus pocketed, as will be understood, with the result that such machines are not available for completely emptying the ove il-and must unnecessarily be shifted-from side to" side otthe oven door, the remainder being removed later by hand} or permitted to remain and he wasted. The

effort to remove this pocketed coke frequently results in damage to the curved jambs, and in the case of hand-drawn ovens the conditions are practically the same. ,7 \Vith an oven of the design contemplatei'il by the present invention. all portions im= ni'erliatcly above the floorarc accessible to the mechanical or hand drawer for removinn all the coke with the least amount of labor and the minimum shifting of the me- (-hanical coke drawer or hand scraper.

the Wall parts.avhieh fori'n the janihs'tor door opening 4,'these jamhs supporting:the door arch 5. Cast-iron frame at'is usually fitted to the outer faces of the jambs. (Each. of the jambs may be formed of several blocks superposed one upon the other. in the present adaptation, the blocks are three high, 6 designatingthe lowermost blocks, 7 the'intermediate blocks, and 8 the uppcn most blocks. It will bedmderstood. howthree-high there are two courses of these bllocks, the inner course 5) being intermediate the wall parts 3 and the outer course 10. Itwill' be understood. howeve ghthat the number of courses may vary.

Blocks 6 are formed with flat: inner faces 11, so that upwardly from tloor :3 a distance corresponding to the height of blocks 6. a straight line may be extended" imvardly through any part ofthe door opening 4, and along said faces 11 and intersect wall 3 without crossing or pocketing any or". the oven space. From this it will be understood'that the rake or fork of a coke drawing machine or a hand scraper, operating through door opening 4. may quickly. and readily gain aecess to all portions of the oven lloor, no part being pocketed andinaccessihle and without being required to repeatedly s the posh tion. of the mechanical drawer or hand scraper. As the drawingrlser yer or other .tool operates on the bottom of the oven, it is sufiicient if all parts immediately above the door can be reached.

The second tier 7 of the lamb hlos zr curred'on their inner surfaces a tilt. sated a at ]2.such curvature increasing vertically and being eontinuer. and terrain; n. ro tinw atlon of the similar. though n u ing, curvature 13 of the uppermost bl: t :e

latter being ofsuflicientsiae or area to sup-- port the door arch g f I "While the invention is designedprimarily for ovens 0t bee-hive type. and is so illus trated, it may be employed in anyoren having curved walls adjacent to the door opening." I clainiz- 1. A. coke oven having a bottom. and horizontally curved side Walls provided with an entrance, door jambs at the oven entrance formingcohtinuations of the inner side of the sidewzills, the lower portion of the inner surface ofthe jamlos being a vertical plane ever, that the number may vary. In the present adaptation, in addition to being-w and arranged so that a straight line may be of the bottom and inner surface of the oven side walls.

2. A coke oven having a bottom, and horizontally curved side walls provided with an entrance, door jambs at the oven entrance forming continuations of the inner side of the side walls, the lower portion of the inner surfaceof the jambs being a vertical plane a distance upwardly from the oven bottom so that a straightline may be drawn from i and through any part of the oven door to any point on'the meeting line of the bottom and inner, surface of the oven side walls, and

the inner surfaces of the upper portions of the-jambs being curved.

3; A bee-hive coke oven havin a bottom, and horizontally curved side wal 5 provided with a door opening extending upwardly from the oven floor, door jambs at opposite sides of the opening and forming continuations of the inner side of the side walls of the oven, the lower portion of the inside of the jambs being a vertical plane so that a straight line may be extended inwardlyfrom any point of the door opening to any oint of the meeting line of the bottomand mner side of the curved side walls of the oven without pocketing any of the oven space, the inner surfaces of the upper portionsof the jambs being in part curved correspondingly to the curvature of the oven walls and in part shaped to conform with the door opening, and an arch for the door opening supported by the said upper portions of the ambs. 1
